The Begining of the End

Who would want to witness a their one gone astray
When the love isnt the same, am I the one to blame?
One second based on instinct can change your perception
catching those words or expressions that stick in your brain
was it the sex? Lack of attention? these insecurities are making me insane
These assumptions are groundless yet inside your heart you know
that the one you would have gave your all too never even cared at all before

...As the truth unravels, all I can do now is be a man and grin and bear it...
